Fire-proof valve is a very important fire-fighting facility in the event of fire, which can play a role in controlling the fire. When fire occurs, the flame invades the air duct, the high temperature melts the fusible alloy on the valve, or makes the memory alloy deform to make the valve shut down automatically, so as to meet the fire-resistant stability and fire-resistant finish in a certain period of time. Integrity requirements, play a smoke-proof and fire-retardant role.
Many fire valves will choose galvanized sheet as the material, because galvanized sheet is the surface of galvanized steel plate, because the surface of galvanized, so it has a very good anti-corrosion effect. Secondly, galvanized steel plate will generally choose high-quality steel plate as the material, so the high-temperature resistance is strong, and the welding performance is very good, so galvanized plate fire valve is also a very high-quality fire valve equipment.
